When you look at some of Michelangelo’s paintings, some of the people in them have halos above their heads. We all know that this means that those people are considered holy and good. But, this is not the case with surveillance. Sometimes, when viewing video from a night vision camera, halo rings will appear in the video. If you see these halo rings, it is definitely not a sign of perfection. It’s also not a ghost, or a UFO, or anything like that. It’s simply the infrared light from the infrared LEDs reflecting off an object nearby the cameras. It could be a nearby window or mirror. The way to fix this is to adjust the cameras where the LEDs are not reflecting off of anything. This is an important factor to keep in mind when installing infrared cameras. You want to ensure that you are recording quality videos at all times, especially at night. God forbid an unfortunate incident happen in front of the cameras at night, and you were not able to see it clearly because of IR reflection.
